Re: 45 CC guns
I strongly considered a PM45, but ended up witb a G36, which is *slightly* bigger. The "beaver tail" on the PM45 dug into the web of my hand a little, plus I really liked (still do) Glocks, and LOVE my G30.
I thought I was buying my end all be all EDC. It had all makings of my perfect EDC... Glock, small, thin, 45! Turns out I almost never shoot or carry it. I like it well enough, but it just doesn't solve anything for me. There is never a time the 36 WILL work, when the 30 WON'T. Between the two, I choose the 30 for ergonomic reasons (big hands-live the fat Glock grip) and CAPACITY.
This was all before I got my PM9. I decided my "new" end all be all EDC was a pocketable singlestack 9mm. Glock doesn't make that, never will...I got the Kahr because it is very Glock like.
I've been TICKLED with my PM9. I have a pocket holster fir it, and it goes everywhere with me where WE'RE allowed to. It has truly been my EDC for over 2 years now. I'm definitely a 45/10mm guy, but the PM9 really suits me well.
Your dilemma: If you are set on a 45, then you must concede some capacity and/or concealability. If you are willing to to do that, the PM45 and G36 are a goid choice, with the Kahr winning on size, and the Glock on shootability - but the Kahr is no slouch. I've come to live the DAO Kahr trigger. Works great just not quite as quick as a Glock.
I don't care for the shootability of the 3" 1911s. They are manageable, but bark a lot more than the little plastic ones.
